create grails custom ResourceMapper

Question

I created the following resource mapper using the instructions from the resources plugin:

import org.grails.plugin.resource.mapper.MapperPhase
import org.apache.commons.logging.LogFactory

class VersionResourceMapper {

    def phase = MapperPhase.MUTATION
    def log = LogFactory.getLog(this.class)

    static defaultIncludes = [ '/js/**' ]

    def map(resource, config) {
        def query = [v:'1.01']
        resource.actualUrl = resource.actualUrl + '?' + query.collect { it }.join('&')
        //resource.updateActualUrlFromProcessedFile()

        if (log.debugEnabled) log.debug "Modified URL: ${resource.actualUrl}"
        log.info "Modified URL: ${resource.actualUrl}"
    }
}

The file is located in grails-app/resourceMappers

My class never even gets called. I have a debug breakpoint set which is never hit. Is there some other configuration that has to be set?

Answer 1

I'm pretty sure that you need to change

def phase = MapperPhase.MUTATION

to

 static phase = MapperPhase.MUTATION

Answer 2

remove this line

static defaultIncludes = [ '/js/**' ]

and check if your breakpoint is hit. It looks like it is just not finding the js directory.

If that works change the above line to

static defaultIncludes = [ 'js/**' ]
